The invention belongs to the technical field of wet braking, and particularly relates to a lever reinforcement type brake cylinder. A piston is cooperatively inserted into a piston cavity of a pump body, a return spring is arranged between the lower end of the piston and the bottom end of the piston cavity, the upper end of the piston extends out of the piston cavity and a push rod is vertically inserted into the upper end of the piston, a zipper connector, an oil inlet connector and a vent hole are formed in the closed end, corresponding to the piston cavity, of the pump body, a supporting column is vertically arranged on the outer cylindrical face of the other end of the pump body, an ejector rod groove is formed in the extending end of the supporting column, an ejector rod is inserted into the ejector rod groove, a pin hole is formed in the position, between the ejector rod groove and the piston cavity, of the corresponding supporting column, the ejector rod groove and the piston cavity are consistent in arrangement direction, and the pin hole and the piston cavity are perpendicular in arrangement direction; and the linear distance L1 from the pin shaft to the piston is a long arm of a lever, the linear distance L2 from the pin shaft to the ejector rod is a short arm of the lever, L1/L2 is larger than 1 and smaller than 10, and the brake cylinder is a lever reinforcement type brake cylinder and can effectively reduce oil pressure needed by a brake system. The brake cylinder is compact in structure and has the functions of service braking and parking braking.
